Specification of Letters Patent.

Patented May 13, 1919.

Application filed September 7, 1918. Serial No. 253,030.

To all whom it may concern:

Be it known that I, DANA OSGOOD, a citizen of the United States, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in known to those skilled in the art, a: feeler isv employed which upon the beat up of the lay enters the shuttle recess and contacts. with the mass of filling upon the filling carrier. The feeler mechanism isso constructed that, when the running filling has reached apredeterminededegree of exhaustion or has become entirely exhausted, the feeler has a side motion, usually due to it, or some portion of it, slipping on the smooth surface of the filling carrier, and this side motion is utilized to effect the initiation of filling replenishment or other change in the operation of the loom.:

' The object of this invention is:to provide a shuttle having means for preventing a premature sidemotion of the feeler taking place and consequently a premature replenishment of the shuttle with a fresh filling carrier or other premature change in the operation of the loom.

The danger of such premature action,

which this invention prevents, arises chiefly from the not infrequent mis-positioning of the shuttle longitudinally at the time the feeling action occurs. Thismis-positioning of the shuttle is due to a slight rebound or a failure fully to enter the shuttle box at the feeling end of the loom and in either case results in bringing the path of feeler movement nearer the butt end of the shuttle recess than the normal path of feeler move-' Serial No. 254,230 filed September 16, 1918,

the broad invention for securing the desired object is disclosed and is shown in its preferred form embodied in ashuttle in which the usual feeler slot-in the shuttle wall is extended toward the butt end of the shuttle recessso as to expose the means, such as the usual metal clamping guide, for holding the butt of the filling carrier, and in which the surface thus exposed is provided with serrations suflicient to prevent side motion of the feeler when the feeler is in contact therewith.

The present invention, which is subsidiary to the aforesaid broad invention, eliminates any extension of the feeler slot beyond that required for the normal feeling: action and provides the shuttle with the required serrated surface on: its outer wall adjacent, and longitudinally in line with, that end of the slot nearer the butt end of the shuttle recess and preferably this serrated surfaceis formed in the material of the shuttle body itself. Thus an. extremely simple and. eflicientconstruotion for effecting the desired result is secured.

The nature and object. of the invention w1ll appear more fully from the accompanying description and drawing and will be partlcularly pointedv out in the appended claims:

In the drawingswhich represent thepreferred form of the invention,

. Figure l is; aside elevation of the end'of a shuttle;

Itig; 2'is atop plan view of the shuttle wlththe butt and a portion of thebarrel of aifilling carrier indicated in dotted lines;-

Fig. 3 is a view in. cross sectiontaken on the line*A.A, in: Fig. 1.

From the statement already made it will be apparent that the construction and operationof the loom and of a side motion feeler mechanism is unchanged by this invention which has to do only with the construction of the shuttle itself. Consequently this description is restricted to the shuttle.

In its general construction the shuttle may be of any usual type. In the preferred form illustrated the body of the shuttle is provided with the usual recess 1 extending through the shuttle from top to bottom to receive the filling carrier which, as indicated in dotted lines, may be a wooden bobbin 2 of usual type. Such a filling carrier is com monly clamped and held in the shuttle recess 1 by a bifurcated metal clamping guide ofv usual construction. The shank 3 of this clamping guide is rigidly secured in the body of the shuttle wlth the arms L and 5 pro ecting into the recess 1 substantlally parallel to the side walls 6 and 7 thereof. The inner surfaces of these arms are usually rooved at 8 to cooperate with rings 9 on the utt of the filling carrier in accurately positioning and firmly holding ,the filling carr1er. 1

The side wall 7 is slotted longitudinally at 10 opposite the axis of the filling carrier to enable the feeler toenter the recess 1 and feel the filling on the filling carrier. In the case of a side motion feeler mechanism, with which the shuttle of this invention is to cooperate, the feeler entering the slot 10 upon the beat up contacts With the filling carrier; if the required amount of filling is present side motion of the feeler is absent, but, if the filling has became exhausted or has reached a predetermined degree of exhaustion, then the feeler contacting with the relatively smooth and hard surface of the filling carrier undergoes some sort of side motion depending upon the character of the specific feeler mechanism employed and this side motion is utilized through a suitable train of mechanism to initiate filling replenishment or other change in the operation of the loom.

But, as already pointed out, longitudinal mis-positio-ning' of the shuttle at the time of feeling, due to rebound orimproper boxing of the shuttle or other cause, will so relate the shuttle to the path of feeler movement that the feeler will not be opposite the filling on the filling carrier but will be in a position opposite a point nearer the butt of the filling carrier or the butt end of the shuttle recess. Under such conditions, when the beat up occurs, the feeler contacts with a smooth hard surface which has no relation to the conditlon of the filling on the filling carrier and consequently side motion may take place resulting in premature initiating action of the feeler mechanism.

This result is obviated in the present invention by providing a serrated surface on the outer wall of the shuttle adjacent, and longitudinally in line with, that end of the slot 10 nearer the butt end of the shuttle recess. This serrated surface is preferably presented by forming vertical ridges and grooves 11 in the material of the shuttle body which is usually composed of Wood but any suitable means for presenting the serrated surface in the specified location may be em ployed. So also the term serrated is to be taken to include any form of roughness snfiicient to prevent side motion of a feeler in contact therewith.

Thus it will be seen that a simple and efficient construction is provided which prevents premature side motion of the feeler with its consequent premature initiation of filling replenishment or other change in the operation of the loom when feeling takes place with the shuttle longitudinally mispositioned.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A shuttle for use in side motion feeler looms provided with a filling carrier recess and with means to clamp and hold a filling carrier by its butt in said recess, one Wall of said recess being slotted to permit the passage of the feeler therethrough, the said shuttle being further provided on its outer wall with a serrated surface adjacent, and longitudinally in line with, that end of the slot'nearer the butt end of the shuttle recess whereby, if the shuttle be longitudinally mispositioned at the time of feeling, the feeler contacting with said serrated surface will be prevented thereby from premature side motion.

2. A shuttle for use in side motion feeler looms having the construction defined in claim '1 in Which the said serrated surface is formed in the material of the shuttle body.

In testimony whereof, I have signed my name to this specification.

' DANA OSGOOD.
